FEED-WATER H EATER.

SPECIFICATION formingpart of Letters Patent No. 352,464, dated November9, 1886.

Application filed June 17, 1886. Serial No. 205,414.

.To aZZ whom, it may concern.-

Be it known that I, GEORGE GREEN, of Gorpus Christi, in the county ofNueces and State of Texas, have invented'a new and Improved FeedaterHeater-for Steam-Boilers, ot' wh ich the following is a full, clear, andexact description.

The object of my invention is to provide a boiler with a feed-waterheater which will serve as a spark-arrester, andwhich will also purifythe water and prevent the formation of scale'in the boiler, and whereby,also, the heating-surface will be increased and fuel economized.

The invention consists of a feed-water heater composed of a series ofpipes attached to halt cylindrical heads, placed diagonally in thefire-box of the boiler, and connected with the waterspace of the boiler.

The invention also consists of various parts and details andcombinations of the same,as will be fully described hereinafter, andthen pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both figures.

Figure 1 isa longitudinalsectional elevation of my improvement, and Fig.2 is a sectional plan view of the same on the line 00 x of Fig. 1.

The boiler A is provided with the firebox B, the fines G, and thegratebars D, of the. usual construction. In the fire-box B is placeddiagonally the feed-water heater E, which conand is provided on eachside with the pipes J,

(No model.)

The feed-water passes from the inlet-pipe H into the feed-water heaterE, and through the same and out into the water-compartment K of theboiler by means of the pipe J.

It will be seen that thewater passing through the feed-water heater E isquickly heated, as the latter is in direct contact. with the fire on thegrate-bars D. The water in the heater E is purified by being heated, theim purities settling in the head G, so that the water which passes intothe water-compartment K is prevented from forming scales in the boiler.It will also be seen that the cinder-s, sparks, &c., are arrested bycoming in contact with the pipes F and the heads G and G of the heaterE, which .dctlect the sparks; back into the fire on the grate bars 1),which consumes the sparks. Sufficient space is left between the pipes Ffor the passage of the heat and smoke from the grate-bars to the linesof the boiler.

Having thus fully described my invention, claim as new and desire tosecure by Letters Patent 1. in a boiler, the combination of a lire-boxwith a feed-water heater consisting of pipes opening intohalf-cylindrical heads, an inletpipe connected with one head, and anoutletpipe connecting the other head with the watercompartment of theboiler, substantially as shown and described.

2. In a boiler, the fire-box B, the boiler-fines O, the gratebars D, andthe water-compart ment K, in combination with the feed-water heater E,consisting of the pipes F and the heads G and G, the inlet-pipe H, andthe out let-pipes J, connecting the head G with the compartment K of theboiler, substantially as shown and described.
